Overriding a Rails default_scope

If I have an ActiveRecord::Base model with a default-scope:

class Foo < ActiveRecord::Base

  default_scope :conditions => ["bar = ?",bar]

end

Is there any way to do a Foo.find without using the default_scope conditions? In other words, can you override a default scope?

I would have thought that using 'default' in the name would suggest that it was overridable, otherwise it would be called something like global_scope, right?

If all you need is to change the order defined in default_scope, you can use the reorder method.

class Foo < ActiveRecord::Base
  default_scope order('created_at desc')
end

Foo.reorder('created_at asc')

runs the following SQL:

SELECT * FROM "foos" ORDER BY created_at asc
